VGA Palette Emulator

[UsefulVideos]

With the instructions of Copilot AI, I have attempted to create a palette emulator in my csmwrap fork but the colors under 32-bit color mode look wrong (tested hardware is ASUS x509FA, UEFI Class 3, Coffee Lake, winload 16497 with vbemp.sys (from AnaPa) if I take screenshots, it looks normal but on the physical display it looks different):

Is there any reason why it's like this?
The scope is to emulate the color palettes so that more legacy color modes can be used, just like what virtual machines do (UEFI hardware sees it as 32-bit color, but OS sees it as the selected color mode).

@FlyGoat This is something I added in the code using Copilot with the intention of emulating other color modes different than 24-bit in CSMWrap in order to improve graphics.
